Dr. Mike Israetel critiques a 16-year-old's public steroid use, explaining that teens using trenbolone and testosterone risk permanent brain development stunting, early growth plate closure (losing 1-3 inches of height), baldness, infertility, and skin issues — while the muscle gains are achievable naturally with a few more years of training.

He argues that teenage desire for quick results is understandable but short-sighted: '30 shows up a lot sooner than you thought,' and the costs include reduced intelligence, emotional instability, and a 'short king forever' outcome.

The expert distinguishes between body dysmorphia (distorted self-perception) and a normal teenager's high risk tolerance — this isn't a medical disorder, just 'teens doing teen shit' with disastrous trade-offs.

He advises that if a teen is already on steroids, the best move is to lower the dose and stop as soon as possible with medical help to restart natural testosterone, and that real 'looks-maxing' comes from sleep, nutrition, hard training, and simply maturing.

Natural teen muscle-building protocol
WhatAchieve a jacked physique without steroids by prioritizing sleep, hard training, excellent nutrition, and simply allowing puberty and time to do the work.
WhenThroughout teenage years and into early 20s; no rush, as peak attractiveness and muscle maturity come in late 20s and 30s.
DoseConsistency for a few years; 'just for twice as long' as the steroid-accelerated timeline.
For whomAny teenager who wants to be lean and muscular, specifically those tempted to use anabolic substances.
WhyNatural gains are substantial, and waiting avoids permanent brain, height, hair, and skin damage; the adult version is taller, smarter, and emotionally stable.
CaveatsRequires patience and long-term thinking, which is difficult for teens. Results will not be immediate but are real and lasting.
Israetel frames this as a 'research lab monk cybertech warrior mode' approach: accept that you aren't getting the rewards now, and build yourself in a disciplined way so that later you emerge as the best version. He emphasizes that the natural trajectory from pudgy teen to jacked adult is extremely common — half of Egypt apparently looks like Zaid without drugs — so the drugs are unnecessary. The 'just wait' message is supported by his own life story of being a short, fat, ugly 15-year-old who later had a great life.
Mechanism
Adolescent male testosterone naturally surges, supporting muscle protein synthesis without exogenous risks. Sleep and nutrition optimize endogenous hormone production and recovery, while training provides the stimulus. The growth plates remain open, allowing full height, and the brain develops without androgenic disruption, preserving cognitive and emotional health.
Personal experience
At 15 he was fatter, uglier, and shorter and got no romantic success; later, without teen drug use, he built a physique and had 'a substantial amount of people thinking I'm cool' and 'swam in it for quite some time.'
The way you're going to look better is getting lots of sleep, training hard, getting excellent nutrition and just growing up.

“You can just get just as jacked as a teen if you wait another few years.”— Clarifies that the end point is the same, just without the damage.
“Same amount of work. Just for like twice as long.”— Highlighting that the effort is equal, only the timeline differs.
Harm reduction protocol for teens already on steroids
WhatImmediately lower the dose and work with a medical professional to safely stop steroids and restart endogenous testosterone production.
WhenAs soon as possible, ideally now; the longer they stay on, the worse the permanent damage.
DoseLower the dose as a first step, then discontinue fully with medical guidance.
For whomAny teenager currently using anabolic steroids, particularly trenbolone or high-dose testosterone.
WhyEvery additional week on supraphysiological androgens deepens the neurological, hepatic, and cardiovascular harm and further cements growth plate closure; stopping early salvages what remains of height, hair, and brain function.
CaveatsStopping abruptly may cause severe hypogonadism and psychological distress; medical supervision is critical to manage withdrawal, monitor lipids, and potentially use PCT (though he doesn't specify compounds). Fertility and sexual function may already be impaired.
Israetel directly addresses Zaid with compassion, acknowledging him as a 'good kid' making dumb choices, and urges him to stop now to salvage height, hair, and mental health. He warns that staying on will only worsen all side effects, and the sooner the escape, the better the long-term outcome. He frames it not as moralizing but as a practical investment in future self.
Mechanism
Exogenous androgens suppress the hypothalamic-pituitary-gonadal axis; upon cessation, the body may not resume normal LH and FSH production without assistance. Medical intervention can include monitoring and possibly pharmacological support to stimulate the testes. Meanwhile, removing the androgens allows growth plates a chance to remain open if they haven't already fused, and reduces neurotoxicity burden.
Personal experience
He notes that even starting at 27 was a bad idea, implying he understands the pull but knows the cost. He offers the advice as someone who has been inside the bodybuilding world.
If you're not going to quit the shit, just lower the fucking dose. ... If you stop them now and you make sure your testosterone is back working again with a medical professional, you're going to have like you know, you're going to pay some downsides, but the longer you stay on it, the worse it'll get.
Also said
“You still want to have your head of hair and still want to be tall and stuff, the sooner you stop the steroids, the better.”— Ties the motivation to the teen's own goals — looks-maxing.
Check your biases with an AI chatbot before making big decisions
WhatIf considering steroids or any extreme move, talk to a neutral AI chatbot like ChatGPT and ask honestly whether it's a good idea.
WhenBefore making a decision, as a sounding board against social media echo chambers.
For whomTeens considering steroids or other high-risk behaviors based on curated online content.
WhyAI will synthesize known risks without the social reinforcement bias, likely talking a teen out of dangerous choices.
CaveatsNot a replacement for medical advice, but a quick, accessible reality check. The AI's answer depends on its training data, but it's better than a biased YouTube feed.
Israetel mentions this after discussing how social media feeds teens exactly what they want to hear. An AI, prompted neutrally, will aggregate the medical consensus and warn about brain damage, height loss, etc., serving as a pocket-sized anti-steroid intervention that doesn't rely on an adult they distrust.
If you're a teen and you're thinking about using steroids, just talk to your favorite AI chatbot and be like, 'Yo, bro, real talk, is this a good idea?' He's probably going to talk you off the ledge.

Teen steroid use as a high-risk tolerance choice, not body dysmorphia
Israetel rejects the medicalization of teen steroid use as body dysmorphia, framing it instead as a rational but foolish cost-benefit decision by a teenager with a high risk tolerance.
Why this matters: He pushes back against the UC San Francisco pediatrics professor's suggestion of body dysmorphia, offering a more nuanced view that doesn't pathologize normal teen impulsivity.
Background
The news segment featured an expert claiming Zaid had body dysmorphia. Israetel argues that true body dysmorphia is when someone like a jacked, lean person perceives himself as small or fat. Zaid was pudgy and short as a teen and wanted to look better — that's not dysmorphia, it's a teenager wanting what most teens want.
Israetel stresses that teens are smart enough to know when adults lie, so telling them looks don't matter backfires. He concedes looks do matter, but steroids as a teen won't actually improve long-term attractiveness because they cause baldness, bad skin, red complexion, and shorter stature — the very things teens hope to avoid. The better path is to accept the slow natural progress, which yields a taller, smarter, more emotionally stable adult who can be 'James Bond in his 30s'. He advises teens to 'recess into this shit, do that, eat' and build themselves over time.
Personal experience
He shares that at 15 he was fatter, uglier, and shorter than Zaid and got 'a whole lot of none' of the things teens want, yet later in life he swam in it for quite some time, proving that a regular person can accomplish a lot without drugs by waiting.
Body dysmorphia is when you look a certain way, but you perceive that you look a very different way. ... When you are a young teenager and you are pudgy and short and not interesting to look at and you think that you want to look jacked and lean, you don't have body dysmorphia. You're just a teenager.
Also said
“There's a thing you want and you accept the risks, right? Like if you are like, 'Hey, I really want money and I'm an unethical person and I'm willing to accept a lot of risks.' You just rob a bank. You don't have like bank dysmorphia or money dysmorphia. You're just a person who's doing some shit that's really dumb.”— Reinforces his argument that this is a choice driven by values and risk tolerance, not a mental illness.
“This looks-maxing thing um subsumes the things that really matter in life like character and integrity and kindness, the things that will carry you throughout the course of your life.”— Shows that he still values character, even as he acknowledges looks matter — adding depth beyond just 'looks don't matter'.
Steroid use permanently stunts brain development and height in teens
Exogenous androgens cap brain development, making the user more aggressive, emotional, irrational, and less intelligent, while high estrogen conversion closes growth plates early, costing 1-3 inches of adult height.
Why this matters: He provides a concrete biological mechanism tied to two catastrophic, irreversible outcomes that teens often overlook when chasing quick muscle.
Background
Previously, drug education often focused on liver toxicity, acne, or 'roid rage', but Israetel highlights the under-discussed neurological and skeletal consequences unique to adolescents.
Israetel explains that for teenagers under 18, and even under 25, reward circuitry and prefrontal cortex development are still underway. Flooding the system with supraphysiological androgens derails that maturation, leading to permanently altered emotional regulation and cognitive ceiling. Additionally, testosterone aromatizes to estrogen, and high estrogen is a primary signal for epiphyseal plate closure. Teens taking high-dose testosterone and other aromatizing compounds essentially guarantee early fusion, trading current muscle for future height — a trade he illustrates with a humiliating club scenario where a short king fails to get attention.
Personal experience
He notes he started steroids at 27 and still considers that a bad idea, but at least he was past the critical windows for height and brain development.
One of the biggest downsides is a potential to cap your brain development and steer it in a way that makes you more aggressive, more emotional, more irrational, and less intelligent for the foreseeable future of your life. And the other big one ... it will cap your growth plates and close them early because of the high estrogen influx from the conversion.
Also said
“So, if you're taking a lot of testosterone and a bunch of other steroids, not all steroids, but for sure testosterone, then the probability that your growth plates close early is high. And this In order to become like jacked when you were 17, you might be trading one, two, maybe three inches of adult height off of your future. You don't get that back.”— Quantifies the height loss and emphasizes irreversibility.
“When did I start steroids? 27. Still probably a bad idea, right?”— Lends credibility: even the expert admits his own early use was misguided, but the teen stakes are far higher.
The 'tren scale' — being jacked on tren has a much higher bar
Once you use trenbolone, your physique is judged against other tren users; being under 225 lbs at 8% body fat while on tren is embarrassing within the drug-using subculture.
Why this matters: Exposes the internal subculture logic that teens don't realize: using the most powerful steroids raises expectations so high that most users still fall short.
Background
Teens see Instagram influencers who are on tren and think they'll look similarly impressive, not knowing that within that world, those physiques are considered inadequate if not at the extreme end.
Israetel says that the bottom of the tren scale is 225 lbs at 8% body fat, and the top is Ronnie Coleman in his prime. A teen on tren who weighs less than that and thinks he looks jacked will be met with derision by anyone familiar with the drug scene. This means the social validation they seek from other lifters will actually backfire, adding humiliation to the health damage. It's a lose-lose: they destroy their bodies and still don't get the respect they imagine.
Once you use tren, you're not rated on a scale of are you jacked or not. No, no. You're rated on a scale of are you jacked for being on tren? The bottom of that scale starts at 225 lb with 8% body fat. The top end of that scale ends at Ronnie Coleman in his prime.
Also said
“So when you take tren and you're like, 'I'm fucking jacked.' And other people who are around the drug world find out you're taking tren, if you weigh under 225 it's embarrassing. You should be embarrassed.”— Directly warns teens that they will be mocked, not admired.
Social media's role in teen steroid decisions is overstated
While the interviewed teen says he wouldn't have used steroids without social media, Israetel counters that teens were using steroids heavily in the 80s and 90s before social media existed.
Why this matters: He challenges the easy narrative that social media is the primary cause, instead emphasizing inherent teen psychology and risk tolerance.
Background
The UC San Francisco professor connected the trend to social media pressure. Israetel acknowledges social media amplifies problems but says the root cause is the same teen impulsivity that has always existed.
He argues that social media's harm lies in its ability to create echo chambers that reinforce what teens want to hear and filter out cautionary messages. However, the drive to use steroids comes from the timeless desire to be 'the fucking man' and 'swim in it', not from a new pathology. He suggests that just talking to an AI chatbot would talk most teens off the ledge because even a neutral source sees the flaws, proving that the issue is access to biased information, not an unprecedented disorder.
Teenagers were using steroids in the '80s and '90s and 2000s all without social media. Social media for some teenagers can be especially harmful because it puts a shit load into their face of information with basically no context and it literally gives them a lot of reinforcement about they would like to hear and very little about they would want to hear.
Also said
“Do you think you would have gotten on steroids without social media? Um no. He's probably right. The answer is probably not. Um It's highly speculative.”— He concedes the teen might be right about his own case, but still pushes back on the broader generalization.
Girls don't value extreme male muscularity; steroids ruin attractiveness features they do care about
Israetel states that women almost never care about extreme jackedness; the male ideal to them is 'Harry Potter with 5 lbs of muscle'. Steroids cause baldness, acne, and weird skin that actually reduce attractiveness.
Why this matters: He redirects the looks-maxing argument by pointing to what women find attractive, undermining the very goal of the teen.
Background
Teens believe getting huge will make them irresistible. Israetel argues that male peers value muscle far more than potential female partners do, and the side effects (hair loss, skin issues) harm appearance more than the muscle helps.
He uses a humorous analogy: 'if Harry Potter gained 5 lbs of muscle and lost 5 lbs of fat' — that's the female ideal. Meanwhile, steroids make you red, blotchy, bald, and emotionally volatile, all of which are repellant. The teen's strategy is counterproductive: they sacrifice height, hair, skin, and mental stability for a physique that gives them only passing respect from other guys, not the romantic success they seek.
Personal experience
He again references his own life: he looks like himself and still 'swam in it' for quite some time, so a regular non-disfigured person can do even better naturally.
Other guys think it's cool that you're jacked in passing. Girls just really almost never give a shit. And for them, what jacked is is like if Harry Potter gained 5 lbs of muscle and lost 5 lbs of fat. That's it.
Also said
“They make you red and way more jacked way faster. You can just get just as jacked as a teen if you wait another few years. The looking good part is something you don't need steroids for. They fuck you over like that.”— Directly ties to his overall argument that steroids are a net negative for looks.
Trenbolone is one of the most toxic steroids, developed for livestock not humans
Trenbolone is a Schedule III veterinary anabolic steroid, extremely toxic to humans, yet easily accessible and used daily by teens who learned to inject from YouTube.
Why this matters: He emphasizes the absurdity of injecting a cattle drug based on a few videos, underscoring the risk with the specific compound.
Background
Many teens think 'steroids' are a monolith; Israetel highlights trenbolone's special toxicity — reddish color infamous in bodybuilding, not meant for humans.
The compound was originally designed to bulk livestock before slaughter. It has no human medical use and carries severe androgenic and cardiovascular risks disproportionate to even other steroids. Zaid injecting it daily exemplifies how social media bypasses any gatekeeping. Israetel's horror is that possession of this Schedule III substance is avowedly illegal, yet done openly in gyms.
This is like the strongest one you can basically get or take. Right. One of the most toxic. >> Yeah, one of the most toxic. All right. Yes, that's bad. That's tren. ... Tren, short for trenbolone, is a powerful anabolic steroid developed for livestock. Sweet. That part's cool. Not humans. Not cool.
Also said
“That you are injecting into your body every single day. >> Yeah, I mean they use it on cows.”— Highlights the daily use of a non-human drug.
